.... incorporates complex constructs such as computations (functions and procedures) some object oriented paradigms, such as instantiation [Bak98, Zhe02] and nested relations [He97, Hao98] The event handler [Sun00] which is a characteristic of active database systems, and attribute metadata [Mer01] for relational OLAP and data mining are implemented in JRelix. A GIS Editor [Che01] is also implemented which demonstrates JRelix capability to support sophisticated data. 1.5 Approach in the thesis In this section, we are going to present our approach ALDATP for implementing a distributed ....
....domain of values. The domian of a given attribute determines its data type. There are two kinds of domain declaration in JRelix, i.e. atomic typed domain and complex typed domain. JRelix provides ten atomic data types: integer, short, long, oat, double, boolean, string, text, universal [Mer01] and attribute [Mer01] type. In general, the syntax used to declare a domain of atomic data type is as follows: domain dom name1 , dom name2 . data type ; The following are example of declaring atomic typed domains. domain dept, office, code, name, title, address string; domain ....
